Clean up crew for reef aquariums, what do they do??

The most useless life in your aquarium are the cuc, if not applied to algae or possibly cyano, the rest do not take crap out of your tank, they eat it and pee and shit there!!!!!!
They making more of the worst ammonias and the worst of ammonias are the types that come out of the tank life, crustaceans are the worst of all!
Fish recycle their pee and corals recycle most of there waste, well sps especially.
CUC or clean up crew is a made up thing of supposed good, the term literally means crap creators!!!!
You know when there is left over crap in your tank, you know what happens to it? bacteria set up shop on it making far less detrimental ammonias and only use roughly 5 percent of that craps phos anyway, and as the bacteria multiply on that crap, they become planktonic as they leave the crap!
You know what is the best of all types of foods for all types of corals, planktonic bacteria!!!!!!!!!
